RAID (Redundant Array of Independent Disks) helps to divide data storage over multiple disks which provides increased data reliability. FortiManager units that contain multiple hard disks can configure the RAID array for capacity, performance, and availability.

You can view the status of the RAID array from the RAID Monitor widget on the System Settings > General > Dashboard page. The RAID Monitor widget displays the status of each disk in the RAID array, including the disk’s RAID level. This widget also displays how much disk space is being used.

The Alert Message Console widget, located in System Settings> General > Dashboard, will provides detailed information about RAID array failures. For more information see “Alert Messages Console widget”.

If you need to remove a disk from the FortiManager unit, you might be able to hot swap it. Hot swapping means that you can remove a failed hard disk and replace it with a new one while the FortiManager unit is in operation. Hot swapping is a quick and efficient way to replace hard disks. For more information about hot swapping, see “Hot-swapping hard disks”.
